Dr. R. Kennedy. Restoration of Paralysed [Apr. 3 T 



to return in the former in 58 days, and in the latter in 42 days, and each of 

 the animals had complete voluntary closure of the eye at about 100 days. 



Of the four dogs, in two the spinal accessory was the substitute nerve, and 

 in two the hypoglossal. Of the two spino-facial anastomoses, one was an end 

 to side, and one an end to end, and the same variation was practised with 

 the two hypoglosso-facial anastomoses. 



The two spino-facial anastomoses commenced to recover voluntary 

 dissociated movements of the face at 105 (end to side) and 90 (end to 

 end) days respectively, and were almost complete as regards power to close 

 the eye at 116 and 123 days respectively. 



The two hypoglosso-facial anastomoses commenced to recover power to 

 close the eye at 55 (end to side) and 84 (end to end) days respectively, and 

 were very complete as regards closure of the eye at 142 and 107 days 

 respectively. 



Association movements of the face, on the normal distribution of the 

 substitute nerve being innervated by the animal, were observed only in two 

 of the experiments, one a spino-facial (end to side) in a monkey, and one 

 a hypoglosso-facial (end to side) in a dog. In the latter case, every rapid 

 movement of the tongue as in eating, licking lips, &c, was accompanied 

 by a wink. 



Secondary Anastomosis. 



The secondary anastomosis experiments were performed in one monkey 

 and three dogs. The monkey had spino-facial anastomosis (end to end) 

 performed one month after section of the facial, and commenced to recover 

 power to close the eye by means of the orbicularis at 46 days, and there was 

 good reflex closure of the eye at 65 days. 



In the three dogs the facial nerve was cut close to the stylo-mastoid 

 foramen and precautions taken to prevent reunion, and anastomosis performed 

 after the lapse of one month in two of the dogs, and after 100 days in the 

 remaining dog. Of the two in which the interval of one month had elapsed, 

 in one, a spino-facial (end to end) anastomosis, no recovery of voluntary 

 function had taken place at 69 days, when the animal died. In the other 

 in which a month's interval had elapsed, a hypoglosso-facial (end to end) 

 anastomosis, voluntary dissociated closure of the eye commenced to return 

 at 60 days and was complete at 93 days. 



In the dog in which 100 days elapsed before substitution, an end to end 

 spino-facial anastomosis was performed, and voluntary closure of the eye 

 commenced to return at 124 and was complete by 167 days. 



In every case except two, a physiological examination was made, and
